Vegetation cover is a critical indicator and sensitive in degradation land. This study aims to explore the comparative analysis of vegetation index in the ex-mine reclamation area. The study is conducted on 2.03 ha area reclamation planted in 2017. The analysis is performed by measure Normalized Difference Vegetation Index (NDVI) from 2017 to 2020 using the Sentinel-2 satellite imagery dataset and processed by ArcGIS Pro 2.6 software. RGB drone photogrammetry acquired in April 2020 and vegetation photos featured with geotagging is used to validate vegetation index analysis. The result shows NDVI first and second-year revegetation demonstrates no significant improvement (less than 0.33), nevertheless third and fourth-year revegetation shows dramatically increase of NDVI, respectively 0.369 and 0.417 with the percentage of healthy vegetation 68.13% and 81.39%. This shows that NDVI and the percentage of vegetation health improve over the year.
Tahapan akhir dari suatu kegiatan usaha pertambangan adalah reklamasi yang bertujuan untuk memperbaiki kualitas lingkungan dan ekosistem sehingga dapat berfungsi kembali sesuai dengan peruntukkannya. Salah satu kriteria keberhasilan reklamasi revegetasi lahan bekas tambang adalah apabila tutupan tajuk telah mencapai ≥ 80%. Tujuan dalam penelitian ini adalah untuk mengalisis komparasi penggunaan metode Vegetation Cover Cassification (Klasifikasi Tutupan Vegetasi) dengan menggunakan data drone dan citra satelit Sentinel-2 dalam menentukan persentase vegetasi dari suatu area reklamasi. Dari perhitungan dengan menggunakan data citra drone yang akuisisi pada 9 Juni 2020 didapat persentase vegetasi 94,43% sedangkan dari pengolahan data citra satelit Sentinel-2 yang di akuisisi tanggal 6 Juni 2020 di dapat persentase vegetasi 94,07%. Dapat disimpulkan bawah penggunaan kedua dataset ini menghasilkan perbedaan persentase tutupan vegetasi yang tidak signifikan (<1%).
